The development of new non-platinum catalysts for alcohol electrooxidation is of utmost importance. In this work, a bimetallic Pd-Cu loaded porous carbon material was first synthesized from a Cu-based metal-organic framework (MOF). The Cu loaded porous carbon was pre-synthesized through calcinating the Cu-based MOF under a N atmosphere. After loading Pd onto the precursor and heating, Pd-Cu loaded porous carbon (Pd-Cu/C) was obtained for alcohol electrooxidation. Electrooxidation experiments revealed that this Pd-Cu bimetal loaded porous carbon assisted steady state electrolysis for alcohol oxidation in alkaline media. Moreover, different alcohols were electrooxidated using the present electrocatalyst for the purposes of discussing the oxidation mechanism. This electrooxidation study of Pd-Cu/C derived from a MOF demonstrates a good understanding of the electrooxidation of different alcohols, and provides useful guidance for developing new electrocatalyst materials for energy conversion and electronic devices.
开发用于醇类电氧化的新型非铂催化剂至关重要。在这项工作中，首先从铜基金属有机框架（MOF）合成了负载双金属钯 - 铜的多孔碳材料。通过在氮气气氛下煅烧铜基MOF预合成负载铜的多孔碳。在将钯负载到前驱体上并加热后，获得了用于醇类电氧化的负载钯 - 铜的多孔碳（Pd-Cu/C）。电氧化实验表明，这种负载双金属钯 - 铜的多孔碳在碱性介质中辅助醇类氧化的稳态电解。此外，使用当前的电催化剂对不同的醇进行电氧化，以讨论氧化机理。对源自MOF的Pd-Cu/C的这种电氧化研究展示了对不同醇类电氧化的良好理解，并为开发用于能量转换和电子设备的新型电催化剂材料提供了有用的指导。
